Commit 2ae416b1 ("mm: new mm hook framework") introduced an empty header file (mm-arch-hooks.h) for every architecture, even those which doesn't need to define mm hooks. As suggested by Geert Uytterhoeven, this could be cleaned through the use of a generic header file included via each per architecture asm/include/Kbuild file. The PowerPC architecture is not impacted here since this architecture has to defined the arch_remap MM hook.

arch/um/kernel/dyn.lds.S and arch/um/kernel/uml.lds.S define some UML-specific symbols. These symbols are used in the kernel part of UML with extern declarations. Move these declarations to a new header, asm/sections.h, like other architectures do. Signed-off-by: NNicolas Iooss <nicolas.iooss_linux@m4x.org> Signed-off-by: NRichard Weinberger <richard@nod.at>

As there are now no remaining users of arch_fast_hash(), lets kill it entirely. This basically reverts commit 71ae8aac ("lib: introduce arch optimized hash library") and follow-up work, that is f.e., commit 23721754 ("lib: hash: follow-up fixups for arch hash"), commit e3fec2f7 ("lib: Add missing arch generic-y entries for asm-generic/hash.h") and last but not least commit 6a02652d ("perf tools: Fix include for non x86 architectures").

The nohz full code needs irq work to trigger its own interrupt so that the subsystem can work even when the tick is stopped. Lets introduce arch_irq_work_has_interrupt() that archs can override to tell about their support for this ability.

Rather than have architectures #define ARCH_HAS_SG_CHAIN in an architecture specific scatterlist.h, make it a proper Kconfig option and use that instead.

In order to promote interoperability between userspace tracers and ftrace, add a trace_clock that reports raw TSC values which will then be recorded in the ring buffer. Userspace tracers that also record TSCs are then on exactly the same time base as the kernel and events can be unambiguously interlaced. Tested: Enabled a tracepoint and the "tsc" trace_clock and saw very large timestamp values. v2: Move arch-specific bits out of generic code. v3: Rename "x86-tsc", cleanups v7: Generic arch bits in Kbuild.

Ease the deployment of clkdev by providing a default asm/clkdev.h for use if the arch does not have an include/asm/clkdev.h. Due to limitations in Kbuild we manually add clkdev.h to all architectures that don't have one rather than having the header appear by default.
